According to foreign media reports, a key factor in the popularization of electric vehicles is the need to have sufficient range, MAHLE (MAHLE) did not use a larger battery to achieve this, but launched a new research and development, integrated heat Battery shell for management functions. This solution can improve the fast charging capacity of the battery and reduce the volume of the power battery by 40%. Therefore, this solution can not only reduce the carbon dioxide emissions of electric vehicles, but also reduce the raw material requirements for battery production. It is important to know that battery materials are becoming scarcer worldwide.
Dr. Otmar Scharrer, Head of R & D and Senior Engineering at Mahle, explained: "Our new battery housing concept can make electric vehicles more economical and environmentally friendly. The battery housing has moderate production costs and can also realize low-cost but powerful batteries , Which is conducive to pushing affordable electric vehicles to a broader market. "
In order to achieve a high level of cooling performance during rapid battery charging, in the MAHLE battery housing concept, the battery is surrounded by a dielectric fluid. The battery case is made of fiber-reinforced plastic, which is not only lightweight but also very strong. Since smaller batteries can be realized, it also allows electric vehicles to achieve weight reduction.
Cooling batteries and electronic components requires complex circuits, greatly increasing the requirements for individual components and thermal management control systems. MAHLE has supported the electrification of power systems and the more stringent requirements associated with it from the beginning, and has been expanding its expertise in research and development.
